[PATCH v10 18/69] drm/display: bridge_connector: Switch to .force_ctx() connector helper

[Cristian Ciocaltea]

Turn drm_bridge_connector_force() into a .force_ctx() implementation and
hand the acquire context over to
drm_atomic_helper_connector_hdmi_force_ctx(), so that the HDMI connector
framework can reset the CRTC to recover the SCDC state when the sink
reconnects while the display pipeline is active.

No functional change for non-HDMI bridge connectors, which keep behaving
as a no-op.
